we, cumpara unu de pe site din china la 23-25 $ si nu te chinui sa inventezi roata, eu te sfatui mai bine din cauza:

cumperi, stii la sigur fa functioneaza.

faci singur, nu stii daca functioneaza, in rezultat: timp pierdut, niervi, si bani pe detalii...

a incercat cineva schema asta?[url=http://www.electroniq.net/scheme-electronice-diverse/detector-de-metale-realizat-cu-mmc4011.htm

Ce ti-ai pierdut ?

L am facut eu dar nu e prea sensibil...

Daca vreti calitate si sensibilitate, recomand schemele de detectoare ce au in componenta mosfet-uri.

De asemenea, cautati sa folositi condesatori cu tantal in loc de cei clasici.
